Application filed May 15, 1908. Serial No. 433,309.

' To all whom it .may concern:

vthe following to be a full, ele-ar, and exact description ot the invention, su'ch as 'will enable others skilled in the art to which it appel-mins to make and use the sanie.` i

@This invention rrelatesto fall boards for pianos, and similar musical instruments, and has tor nn object to provide a tall board folding in improved manner within the case.

.l further object of the invention is to provide a` fall board folding vWithin the minimum amount of space back of the normal closed position ot" the fall board.

With these and other objects in view, the invention comprises vCertain novel constructions, combinations and arrangements of parts, as will be hereinafter itully described and claimed.

In the drawings z-li`igure l is a perspective broken view of the fall board associated with a conventional plinio-case. F ig. 2 is '.1 view in vertical transverse section of the improved fall board associated with a piano case in closed relation shoivinfr in dotted lines the first movement of the opening. Fig. E5 is a vertical transverse sectional View of the improved fall board .folded and open.

Like characters of reference designate correspoiniing parts throughout the several views.

Inthc makin f of player pianos it is found necessaryor at gleast highly desirable to utilize everv possible inch of space Within the case, and t'or such purpose it is desirable to produce a fall board which will occupy but very small amount of space'when folded. For this purpose the fall board here shown i `comprises a substantially L-shaped portion 10 hinged by pivoting at the pivot point l1.

.At the normal outer edge the portion l0 is.

. provided with hinges 12' to Which is hinged a portion or strip 13 in such position as to normally extend outwardly substantially in a 'plane with the longer leg of the L 10 as shown particularly in Figs, l and 2. The parts l() and 13 may be provided With beads 14 and l5 respectively positioned to Contact with each other when the-fall board is extended and to hold in association with the hinges l2 the strip 13 substantially in a plane with the portion 10;

To the normally under side of ith/e strip 13 hinges 1G are secured. and thereto/is hinged a strip i7 which entends Vdownvia'rdly from the strip 13 when extend-ed and in contact .viththe usual ledge 18' ordinarily-found upon a piano'case.

Adjacent the' upper portion 1 9 of .thel case` a strip or abutment 20 is rigidly secured and between the normally npturned portion ot' the L-shaped member 10 and the .said abutment a strip 2l is carried as by the hinge 22 and the upper edge-'of the portionl 10. At the opposite ends of the piano 'case grooves 23 are provided in any Iapproved manner as by means of a strip 24secured thereto as represented in the drawings, The.

strip 21 is provided with pintles 25 in. its

opposite ends positioned to move 'within'the' groove 23 which is set atan inclination'as shown particularly in Figs. 2 and 3. l 4llVith the fall board closed as shown in full lines in Fig. 2 the tirstmotioni'n open-i' ing the same is to raise the strip -lil. upon the hinge 12 to the position shown in dotted line which permits the stri 17 to assume the position also shown in otted lin'esfboth' strips 13 and 17 being then folded down-i' Wardly upon the top of the stri 10'.. The strip l() is then lifted upon itsp vot 1l 'and turned backwardly to the position shown in 3 with the then lowered ed e of the strip 17 resting in the notch provi ed by the bead of the strip 21 which said 'notch or groove also engages the under edge of the strip 20 when t e fall board is extended. It. will be seen that by the several folds em:I

ployed the fall boa-rdis foldedjwithin a minimum amount of space as shown particullarly in Fig. 3.

What .I claim is l. The combination with a piano case rovided with grooves inclined to a-verti'ca of a fallboard hinged to the case, and a member hinged to' the hinged member and provided With means engaging with and slidable in the inclined grooves.

2. The combination with a piano case, of a fallboard hinged to the case, of a member hinged to the outer extremity of the fall4 board and provided with a hinge joint, and

a member hinged to the fallboard and slid-A able relative to the case. l

8. The combination With apiano case prohinged to the fallboard and vided` with grooves inclined to a vertical, of

` a strip hinged tothe l'iinged member and adapted to' 'o ld over and upon the adjaeent edges of the hinged member end fallboard.

.LThe combination with a piano ease, of

a fallboard' member hinged thereto, lof a' member hinged to the fallboard member and extending' upwardly, groove members at opposite ends of the fallboard, and, means can ried by the upwardly extending strip engag ing and traveling in the gi oove member.

5. The combination with a piano case provided with grooves at opposite ends inclined to a vertical, of a allboard member substantially Lshaped in transverse section hinged to' the ease, a strip hinged to the fallboard .member and extending upwardly, means carried by the hinged strip traveling in the inclined grooves, and a hinged strip ,carried by the fallboard member.

G. The combination with a piano ease proi vided with grooves at its opposite ends n- @lined to a vertical, of a substantially L shaped fallboard member hinged inthe case adjacent its angle, and e strip hinged to the upwardly extending portion of the fallboard member and provided with ineens traveling in the grooves.

7. The-combination with a piano case, of a substantially @.shaped fallboard member hinged to the oase adjacent its angle, of a strip hinged to and extending above the lz-shaped strip, means lproviding a movement of the strip downwardly and rearwardly when the L-sheped strip is moved, and a strip hinged to the opposite extremity of the L-shaped member.

S. The combination with e piano cese, of a substantially L-shaped fall board member hinged adjacent its angle, a strip hinged to one extremity of the L-sheped member and extending upwardly, a strip hinged to the opposite extremity of the L-sbaped member and extending outwardly, and a Strip hinged to the last-mentioned strip and extending downwardly.

In testimony whereof I allix my signature in presence of two witnesses.
